The Fisher exact test, chi-square test, Mann-Whitney U test, Wilcoxon test for paired samples, and sign test were applied to the data (α = 0.05). After 3 students in the control group were excluded because they received fixed orthodontic appliances, 37 students participated in the control group and 40 in the experimental group. Both groups presented a 30% reduction in PI (P less then 0.001) after the interventions. The experimental group flossed significantly more frequently (P = 0.003) than the control group. The interventions had no statistically significant effect on GBI, and there were no significant differences in toothbrushing frequency after interventions or between groups. Both approaches to oral health education-conventional and digital-had a positive impact on the reduction of the PI, and the use of a smartphone app seemed to be an effective resource for providing oral health education to students.

In addition to the classically considered features of autism, individuals with this disorder also often present with multiple significant medical comorbidities that affect dental treatment. This article discusses the most common of these neurologic, psychiatric, and gastrointestinal issues and explores their relevance to dental care. It is incumbent on dentists and members of the dental team to be familiar with the features and comorbidities of autism spectrum disorder and effectively use this knowledge to provide care for patients with autism.Gingival recession is a common problem that requires periodontal surgery to restore esthetics. The vestibular incision subperiosteal tunnel access (VISTA) technique is a minimally invasive recession coverage method that has gained popularity. This case series reviews the treatment outcomes in 10 patients with a total of 28 Miller Class I or Class II recession defects in the maxillary anterior region. The defects were treated with the VISTA technique alone without any grafting material. The clinical parameters measured at baseline and at 3- and 6-month follow-up examinations were probing depth, clinical attachment level, Gingival Index, width and thickness of attached gingiva, and height of gingival recession. Statistical analysis (repeated-measures analysis of variance with a post hoc Bonferroni test) revealed that all clinical parameters except probing depth and thickness of attached gingiva showed statistically significant improvement from baseline to the follow-up examinations (P less then 0.001). A mean root coverage of 78.99% was achieved. Even when performed without any grafting material, the VISTA technique is a reliable method to obtain recession coverage in the maxillary anterior region.Clinical decision-making regarding retention and treatment vs extraction and replacement of teeth can be a significant challenge. This systematic review and meta-analysis aimed to assess decision-making in clinical practice related to the retention and endodontic treatment of natural dentition vs extraction and replacement with implant-assisted restorations. The PubMed/MEDLINE, Scopus, Web of Science, and Education Resources Information Center (ERIC) databases were comprehensively searched for studies published through May 31, 2019. https://www.selleckchem.com/products/CP-690550.html All randomized controlled trials and cohort studies that assessed the effect of endodontic treatment/retreatment and implant treatment were included. Primary outcomes included success, survival, and failure rates. Meta-analysis software was used for data analysis. Of 1550 identified articles, 5 were eligible for qualitative and quantitative analyses. All 5 of the included studies reported that both therapies are viable and predictable treatment options. The meta-analysis showed no significant difference between therapies when survival rates were considered to be successes, while a significant difference was found in favor of endodontic therapy when survival rates were considered to be failures. The available evidence suggests that both therapies have approximately similar outcomes, but endodontic therapy provides moderately better outcomes. Endodontic therapy should be considered the first option when possible.This study aimed to evaluate the erosive potential of powdered juice drinks on dental enamel in 2 stages physiochemical characterization and erosive challenge testing. In stage 1, the pH and titratable acidity of 5 commercially available powdered juices in 10 different flavors were analyzed. Five treatment groups were then established based on the pH values, titratable acidity, and presence of citric acid in the juices, and their energy-dispersive X-ray (EDX) spectroscopy profiles were studied. In stage 2, the erosive effect of the juices was tested using a pH cycling model; polished bovine dental enamel blocks (n = 8) were treated 4 times daily on 5 consecutive days with 1% citric acid (positive control) or lemon, orange, pineapple, or cashew juice. The specimens were immersed in the erosive solutions, under agitation (100 rpm), for 1 minute at 25°C. Overnight and between treatments, the blocks were stored in artificial saliva without agitation. At the end of cycling, the enamel surfaces were evaluated by prlead to surface loss of dental enamel.This study evaluated the influence of chewing-side preference on the volume of the mandibular condyle and coronoid process and the dynamic parameters of the temporomandibular joint (TMJ). Cone beam computed tomographic scans of both TMJs of 90 individuals with a chewing-side preference were obtained while the patients were in the closed-mouth and maximum mouth-opening positions (test power ? 0.80). The preferred chewing side was identified with a chewing gum test as well as by patient self-reports of preferred side and hemispheric dominance (ie, dominant side of the body). Two trained examiners assessed the volume of the mandibular condyle and coronoid process and the dynamic parameters of the TMJs on both sides. The volumes of the mandibular condyle on the 2 sides were compared using a paired t test (α = 0.05). McNemar and Bowker tests of symmetry (α = 0.05) were used for concordance analyses of the dynamic parameters of the TMJ on the chewing and nonchewing sides. No statistically significant difference was observed in the volume of the mandibular condyle (chewing gum test, P = 0.
